                                   ARTICLE VII

                                    GUARANTEE

Section 701 Unconditional Guarantee.

            The Guarantor hereby fully and unconditionally guarantees (such
guarantee to be referred to herein as the "Guarantee") to the Holders of the
Notes and to the Trustee and its successors and assigns that: (i) the principal
of and interest on the Notes will be promptly paid in full when due, subject to
any applicable grace period, whether at maturity, by acceleration or otherwise
and interest on the overdue principal, if any, and interest on any interest on
the Notes and all other obligations of the Company to the Holders or the Trustee
hereunder or thereunder will be promptly paid in full or performed, all in
accordance with the terms hereof and thereof; and (ii) in case of any extension
of time of payment or renewal of any Notes or of any such other obligations, the
same will be promptly paid in full when due or performed in accordance with the
terms of the extension or renewal, subject to an applicable grace period,
whether at stated maturity, by acceleration or otherwise (collectively, the
"Guaranteed Obligations"). The Guarantor hereby agrees that its obligations
hereunder


                                       10
<PAGE>
shall be full, irrevocable, unconditional and absolute, irrespective of the
validity, regularity or enforceability of the Notes or the Indenture, the
absence of any action to enforce the same, any waiver or consent by any Holder
of Notes with respect to any provisions hereof or thereof, the recovery of any
judgment against the Company, any action to enforce the same or any other
circumstance which might otherwise constitute a legal or equitable discharge or
defense of a guarantor.

            The obligations of the Guarantor hereunder are separate and
independent of the obligations of the Company, and a separate action or actions
may be brought and prosecuted against the Guarantor whether action is brought
against the Company or whether the Company is joined in any action or actions.
The obligations of the Guarantor hereunder shall survive and continue in full
force and effect until the earlier of (i) such time as the Guarantee shall cease
to exist pursuant to the terms of Section 704 hereof, or (ii) payment in full of
the Guaranteed Obligations is actually received by the Holders or the Trustee on
behalf of the Holders and the period of time has expired during which any
payment made by the Company or the Guarantor may be determined to be a
Preferential Payment (defined below), notwithstanding any release or termination
of the Company's liability by express or implied agreement or by operation of
law and notwithstanding that the Guaranteed Obligations or any part thereof are
deemed to have been paid or discharged by operation of law or by some act or
agreement. For purposes of this Guarantee, the Guaranteed Obligations shall be
deemed to be paid only to the extent that the Holders, or the Trustee on behalf
of the Holders, actually receive immediately available funds.

            The Guarantor agrees that to the extent the Company makes any
payment to the Holders, or to the Trustee on behalf of the Holders, in
connection with the Guaranteed Obligations, and all or any part of such payment
is subsequently invalidated, declared to be fraudulent or preferential, set
aside or required to be repaid by the Holders or the Trustee or paid over to a
trustee, receiver or any other entity, whether under any bankruptcy act or
otherwise (any such payment is hereinafter referred to as a "Preferential
Payment"), then this Guarantee shall continue to be effective or shall be
reinstated, as the case may be, and, to the extent of such payment or repayment
by the Holders or Trustee, the Guaranteed Obligations or part thereof intended
to be satisfied by such Preferential Payment shall be revived and continued in
full force and effect as if said Preferential Payment had not been made.

Section 702 Waiver.

            To the fullest extent permitted by applicable law, the Guarantor
waives and agrees not to assert: (a) any right to require the Holders or Trustee
to proceed against the Company, to pursue any other remedy available to the
Holders or Trustee or to pursue any remedy in any particular order or manner;
(b) assert the benefit of any statute of limitations affecting the Guarantor's
liability hereunder or the enforcement hereof; (c) demand, diligence,
presentment for payment, protest and demand, and notice of extension, dishonor,
protest, demand, nonpayment and acceptance of this Guarantee; (d) notice of the
existence, creation or incurring of new or additional indebtedness of the
Company to the Holders; and (e) any defense arising by reason of any disability
or other defense of the Company or by reason of the cessation from any cause
whatsoever (other than payment in full of all amounts demanded


                                       11
<PAGE>
to be paid by the Guarantor under this Guarantee) of the liability of the
Company for the Guaranteed Obligations. Until payment in full of the Guaranteed
Obligations, the Guarantor shall have no right of subrogation and hereby waives
any right to enforce any remedy which the Holders or the Trustee now have, or
may hereafter have, against the Company, and waives any benefit of, or any right
to participate in, any security now or hereafter held on behalf of the Holders.

Section 703 Execution of Guarantee.

            The Guarantor hereby agrees to execute a notation of Guarantee in
substantially the form attached to the form of Note, and to deliver such
notation to the Trustee.

            The Guarantor hereby agrees that its Guarantee of Securities of a
series to which this Article VII has been made applicable shall remain in full
force and effect notwithstanding any failure to endorse on any such Security a
notation relating to the Guarantee thereof.

            Manual or facsimile signatures of individuals, on this First
Supplemental Indenture and the Base Indenture, who were at any time the proper
officers of the Guarantor, shall bind the Guarantor, notwithstanding that such
individuals or any of them have ceased to hold such offices prior to or at the
time of the authentication and delivery of such Securities by the Trustee or did
not hold such offices at the date of such Securities.

            The delivery by the Trustee of any Security of a series to which
this Article VII has been made applicable, after the authentication thereof
under this Indenture, shall constitute due delivery of the Guarantee set forth
in this Indenture on behalf of the Guarantor.

Section 704 Cessation of Guarantee.

            The Guarantee under this First Supplemental Indenture will
automatically cease to exist upon the merger of the Company with and into the
Guarantor, at which point the Guarantor will succeed to, and be substituted for,
and may exercise every right and power of, the Company under the Base Indenture,
this First Supplemental Indenture and the Notes.

                                  ARTICLE VIII

                                  MISCELLANEOUS

Section 801 Ratification of Base Indenture.

            The Base Indenture, as supplemented by this First Supplemental
Indenture, is in all respects ratified and confirmed, and this First
Supplemental Indenture shall be deemed part of the Base Indenture in the manner
and to the extent herein and therein provided.

Section 802 Trustee Not Responsible for Recitals.

            The recitals herein contained are made by the Company and the
Guarantor and not by the Trustee, and the Trustee assumes no responsibility for
the correctness thereof. The Trustee makes no representation as to the validity
or sufficiency of this First Supplemental Indenture.

Section 803 Governing Law.

            This First Supplemental Indenture, the Guarantee and the Notes shall
be construed in accordance with and governed by the laws of the State of New
York.

Section 804 Separability.

            In case any one or more of the provisions contained in this First
Supplemental Indenture or in the Notes shall for any reason be held to be
invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provisions of this First
Supplemental Indenture or of the Notes, but this First Supplemental Indenture
and the Notes shall be construed as if such invalid or illegal or unenforceable
provision had never been contained herein or therein.

Section 805 Counterparts.

            This First Supplemental Indenture may be executed in any number of
counterparts each of which shall be an original; but such counterparts shall
together constitute but one and the same instrument.

            This Note is a Global Note within the meaning of the Base Indenture
hereinafter referred to and is registered in the name of a Depositary or a
nominee of a Depositary. This Note is exchangeable for Notes registered in the
name of a person other than the Depositary or its nominee only in the limited

            Unless this Note is presented by an authorized representative of The

agent for registration of transfer, exchange or payment, and any Note issued is
registered in the name of Cede & Co. or in such other name as is requested by an

                              DUE DECEMBER 15, 2020

            PRR NEWCO, INC., a corporation organized under the laws of the
Commonwealth of Virginia (herein called the "Company," which term includes any
successor corporation under the Base Indenture hereinafter referred to), for
value received, hereby promises to pay, and Norfolk Southern Railway Company, a
corporation organized under the laws of the Commonwealth of Virginia
(hereinafter called "NSR" or the "Guarantor") hereby promises to fully and
unconditionally guarantee such payment, to Cede & Co., or registered assigns,
the principal sum of [Three-Hundred-Nineteen Million Dollars ($319,000,000)] on
June 15, 2020 and the Company hereby promises to pay, and NSR promises to
guarantee, the payment of interest thereon from [closing date] or from the most
recent interest payment date to which interest has been paid or duly provided
for, semi-annually in arrears on June 15 and December 15 of each year,
commencing June 15, 2004, at a rate of 9-3/4% per annum until the principal
hereof is paid or made available for payment, and on any overdue principal and
premium, if any, at a rate of 9-3/4% per annum and (without duplication and to
the extent that


                                      A-1
<PAGE>
payment of such interest is enforceable under applicable law) on
any overdue installment of interest at a rate of 9-3/4% per annum compounded
semi-annually. The interest so payable, and punctually paid or duly provided
for, on any Interest Payment Date (as defined below) shall be calculated as
provided in the Base Indenture. In the event that any date on which interest is
payable on this Note is not a Business Day, then payment of interest payable on
such date will be made on the next succeeding day that is a Business Day, with
the same force and effect as if made on such date and no interest shall accrue
on the amount so payable from the period from and after such Interest Payment
Date or Maturity Date, as the case may be (each date on which interest is
actually payable, an "Interest Payment Date"). The interest installment so
payable, and punctually paid or duly provided for, on any Interest Payment Date
will, as provided in the Base Indenture, be paid to the Person in whose name
this Note (or one or more Predecessor Security, as defined in said Base
Indenture) is registered at the close of business on the regular record date for
such interest installment, which shall be the close of business on the June 1
and December 1 next preceding such Interest Payment Date. Any such interest
installment not punctually paid or duly provided for shall forthwith cease to be
payable to the registered Holders on such regular record date and may be paid to
the Person in whose name this Note (or one or more Predecessor Security) is
registered at the close of business on a special record date to be fixed by the
Trustee for the payment of such defaulted interest, notice whereof shall be
given to the registered Holders of Notes not less than 10 days prior to such
special record date, or may be paid at any time in any other lawful manner, all
as more fully provided in the Base Indenture. The principal of and premium, if
any, and the interest on this Note shall be payable at the office or agency of
the Trustee maintained for that purpose in any coin or currency of the United
States of America that at the time of payment is legal tender for payment of
public and private debts; provided, however, that payment of interest may be
made, at the option of the Company and upon prior notice to the Trustee, by
check mailed to the registered Holder at such address as shall appear in the
Security Register or by wire transfer to an account designated by a Holder in
writing not less than ten days prior to the date of payment.

            The indebtedness evidenced by this Note is, to the extent provided
in the Base Indenture, equal in right of payment with all other unsecured and
unsubordinated indebtedness of each of the Company and the Guarantor, and this
Note is issued subject to the provisions of the Base Indenture and the First
Supplemental Indenture hereinafter referred to with respect thereto. Each Holder
of this Note, by accepting the same, agrees to and shall be bound by such
provisions, and authorizes and directs the Trustee on his or her behalf to be
bound by such provisions. Each Holder hereof, by his or her acceptance hereof,
hereby waives all notice of the acceptance of the provisions contained herein
and in the Base Indenture and the First Supplemental Indenture by each Holder of
unsecured and unsubordinated indebtedness of the Company, whether now
outstanding or hereafter incurred, and waives reliance by each such Holder or
creditor upon said provisions.

            This Note shall not be entitled to any benefit under the Base
Indenture or the First Supplemental Indenture, or be valid or become obligatory
for any purpose until the Certificate of Authentication hereon shall have been
signed by or on behalf of the Trustee.

            The provisions of this Note are continued on the reverse side hereof
and such continued provisions shall for all purposes have the same effect as
though fully set forth at this place.

            IN WITNESS WHEREOF, the Company and the Guarantor have caused this
instrument to be executed.

<PAGE>
                          (FORM OF REVERSE OF NOTE)

            This Note is one of a duly authorized series of securities of the
Company (herein sometimes referred to as the "Security"), issued or to be issued
in one or more series under and pursuant to an Indenture, dated as of
[__________, 2004] (the "Base Indenture"), duly executed and delivered by and
among the Company, the Guarantor and The Bank of New York (the "Trustee"), as
supplemented by the First Supplemental Indenture, dated as of [__________, 2004]
(the "First Supplemental Indenture"), by and among the Company, the Guarantor
and the Trustee to which Base Indenture and First Supplemental Indenture
reference is hereby made for a description of the rights, limitations of rights,
obligations, duties and immunities thereunder of the Trustee, the Company, the
Guarantor and the Holders of the Security. By the terms of the Base Indenture,
the Securities are issuable in series that may vary as to amount, date of
maturity, rate of interest and in other respects as provided in the Base
Indenture. This Security is the series designated on the face hereof (the
"Notes") and is limited in aggregate principal amount as specified in said First
Supplemental Indenture.

            In case an Event of Default, as defined in the Base Indenture, shall
have occurred and be continuing, the principal of all of the Notes may be
declared due and payable, in the manner, with the effect and subject to the
conditions provided in the Base Indenture.

            The Base Indenture contains provisions permitting the Company and
the Trustee, with the consent of the Holders of not less than a majority in
principal amount of the Outstanding Security of each series affected, to execute
supplemental indentures for the purpose of adding any provisions to the Base
Indenture or of modifying in any manner the rights of the Holders of the
Security; provided, however, that no such supplemental indenture shall (i)
change the Stated Maturity of the principal of, or any installment of principal
of or interest on, any Security, or reduce the principal amount thereof or any
premium payable upon the redemption thereof or the rate of interest thereof to
reduce the amount of principal of an Original Issue Discount Security that would
be due and payable upon a declaration of acceleration of the Maturity thereof
pursuant to Section 502 of the Base Indenture, or change any Place of Payment
where, or the coin or currency in which, any Security (or premium, if any,
thereon) or the interest thereon is payable, or impair the right to institute
suit for the enforcement of any such payment on or after the Stated Maturity
thereof (or, in the case of redemption, on or after the Redemption Date); or
(ii) reduce the percentage in principal amount of the Outstanding Security of
any series, the Holders of which are required to consent to any such
supplemental indenture or to waive certain defaults thereunder and their
consequences provided for in the Base Indenture; or (iii) modify any of the
provisions of the Base Indenture relating to supplemental indentures that
require consent of Holders, the waiver of past defaults or the waiver of certain
covenants, except to increase any such percentage or to provide that certain
other provisions of the Base Indenture cannot be modified or waived, without the
consent of the Holders of each Outstanding Security affected thereby, provided,
however, that the consent of the Holders shall not be required with respect to
changes in the references to "the Trustee" in Sections 802 and 908 of the Base
Indenture or with respect to the deletion of this proviso from the Base
Indenture, in accordance with Sections 608(b) and 801(7) of the Base Indenture.
The Base Indenture also contains provisions permitting the Holders of not less
than a majority in principal amount of the Outstanding Security of any series
affected thereby, on behalf of all of the Holders of the


                                      A-4
<PAGE>
Security of such series, to waive any past Default under the Base Indenture, and
its consequences, except a Default in the payment of the principal of, premium,
if any, or interest on any Security of such series or a Default in respect of a
covenant or provision of the Base Indenture which cannot be modified or amended
without the consent of the Holder of each Outstanding Security of such series
affected. Any such consent or waiver by the registered Holder of this Note
(unless revoked as provided in the Base Indenture) shall be conclusive and
binding upon such Holder and upon all future Holders and owners of this Note and
of any Note issued in exchange therefor or in place hereof (whether by
registration of transfer or otherwise), irrespective of whether or not any
notation of such consent or waiver is made upon this Note.

            No reference herein to the Base Indenture or First Supplemental
Indenture and no provision of this Note or of the Base Indenture or First
Supplemental Indenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay the principal of and premium, if
any, and interest on this Note at the time and place and at the rate and in the
money herein prescribed.

            As provided in the Base Indenture and subject to certain limitations
therein set forth, this Note is transferable by the registered Holder hereof on
the Security Register of the Company, upon surrender of this Note for
registration of transfer at the office or agency of the Trustee in New York, New
York duly endorsed by the registered Holder hereof or accompanied by a written
instrument or instruments of transfer in form satisfactory to the Company and
the Security Registrar duly executed by the registered Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Notes of this
series of authorized denominations and for the same aggregate principal amount
will be issued to the designated transferee or transferees.

            No service charge will be made for any such transfer, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in relation thereto.

            Prior to due presentment of this Note for registration of transfer
of this Note, the Company, the Trustee, and any agent of the Company or the
Trustee may treat the registered Holder hereof as the owner hereof (whether or
not this Note shall be overdue) and neither the Company, the Trustee nor any
such agent shall be affected by notice to the contrary.

            No recourse shall be had for the payment of the principal of or the
interest on this Note, or for any claim based hereon, or otherwise in respect
hereof, or based on or in respect of the Base Indenture, against any
incorporator, stockholder, officer or director, past, present or future, as
such, of the Company, the Guarantor or of any predecessor or successor
corporation of either the Company or the Guarantor, whether by virtue of any
constitution, statute or rule of law, or by the enforcement of any assessment or
penalty or otherwise, all such liability being, by the acceptance hereof and as
part of the consideration for the issuance hereof, expressly waived and
released. Such waiver may not be effective to waive liabilities under the
federal securities laws.

                                      A-5

            The Notes are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof. This Global Note is
exchangeable for Notes in definitive form only under certain limited

hereinafter referred to and is registered in the name of a Depositary or a

                              DUE NOVEMBER 15, 2043

            PRR NEWCO, INC., a corporation organized under the laws of the
Commonwealth of Virginia (herein called the "Company", which term includes any
successor corporation under the Base Indenture hereinafter referred to), for
value received, hereby promises to pay, and Norfolk Southern Railway Company, a
corporation organized under the laws of the Commonwealth of Virginia
(hereinafter called "NSR" or the "Guarantor") hereby promises to fully and
unconditionally guarantee such payment, to Cede & Co., or registered assigns,
the principal sum of [One-Hundred Forty-Five Million Dollars ($145,000,000)] on
May 15, 2043 and the Company hereby promises to pay, and NSR promises to
guarantee, the payment of interest thereon from [closing date] or from the most
recent interest payment date to which interest has been paid or duly provided
for, semi-annually in arrears on May 15 and November 15 of each year, commencing
May 15, 2004, at a rate of 7-7/8% per annum until the principal hereof is paid
or made available for payment, and on any overdue principal and premium, if any,
at a rate of 7-7/8% per annum and (without duplication and to the extent that

                                      B-1
<PAGE>
payment of such interest is enforceable under applicable law) on any overdue
installment of interest at a rate of 7-7/8% per annum compounded semi-annually.
The interest so payable, and punctually paid or duly provided for, on any
Interest Payment Date (as defined below) shall be calculated as provided in the
Base Indenture. In the event that any date on which interest is payable on this
Note is not a Business Day, then payment of interest payable on such date will
be made on the next succeeding day that is a Business Day, with the same force
and effect as if made on such date and no interest shall accrue on the amount so
payable from the period from and after such Interest Payment Date or Maturity
Date, as the case may be (each date on which interest is actually payable, an
"Interest Payment Date"). The interest installment so payable, and punctually
paid or duly provided for, on any Interest Payment Date will, as provided in the
Base Indenture, be paid to the Person in whose name this Note (or one or more
Predecessor Security, as defined in said Base Indenture) is registered at the
close of business on the regular record date for such interest installment,
which shall be the close of business on the May 1 and November 1 next preceding
such Interest Payment Date. Any such interest installment not punctually paid or
duly provided for shall forthwith cease to be payable to the registered Holders
on such regular record date and may be paid to the Person in whose name this
Note (or one or more Predecessor Security) is registered at the close of
business on a special record date to be fixed by the Trustee for the payment of
such defaulted interest, notice whereof shall be given to the registered Holders
of Notes not less than 10 days prior to such special record date, or may be paid
at any time in any other lawful manner, all as more fully provided in the Base
Indenture. The principal of and premium, if any, and the interest on this Note
shall be payable at the office or agency of the Trustee maintained for that
purpose in any coin or currency of the United States of America that at the time
of payment is legal tender for payment of public and private debts; provided,
however, that payment of interest may be made, at the option of the Company and
upon prior notice to the Trustee, by check mailed to the registered Holder at
such address as shall appear in the Security Register or by wire transfer to an
account designated by a Holder in writing not less than ten days prior to the
date of payment.

            The indebtedness evidenced by this Note is, to the extent provided
in the Base Indenture, equal in right of payment with all other unsecured and
unsubordinated indebtedness of each of the Company and the Guarantor, and this
Note is issued subject to the provisions of the Base Indenture and the First
Supplemental Indenture hereinafter referred to with respect thereto. Each Holder
of this Note, by accepting the same, agrees to and shall be bound by such
provisions, and authorizes and directs the Trustee on his or her behalf to be
bound by such provisions. Each Holder hereof, by his or her acceptance hereof,
hereby waives all notice of the acceptance of the provisions contained herein
and in the Base Indenture and the First Supplemental Indenture by each Holder of
unsecured and unsubordinated indebtedness of the Company, whether now
outstanding or hereafter incurred, and waives reliance by each such Holder or
creditor upon said provisions.

            This Note shall not be entitled to any benefit under the Base
Indenture or the First Supplemental Indenture, or be valid or become obligatory
for any purpose until the Certificate of Authentication hereon shall have been
signed by or on behalf of the Trustee.

            The provisions of this Note are continued on the reverse side hereof
and such continued provisions shall for all purposes have the same effect as
though fully set forth at this place.

            IN WITNESS WHEREOF, the Company and the Guarantor have caused this
instrument to be executed.

                            (FORM OF REVERSE OF NOTE)

            This Note is one of a duly authorized series of securities of the
Company (herein sometimes referred to as the "Security"), issued or to be issued
in one or more series under and pursuant to an Indenture, dated as of [________,
2004] (the "Base Indenture"), duly executed and delivered by and among the
Company, the Guarantor and The Bank of New York (the "Trustee"), as supplemented
by the First Supplemental Indenture, dated as of [____________, 2004] (the
"First Supplemental Indenture"), by and among the Company, the Guarantor and the
Trustee to which Base Indenture and First Supplemental Indenture reference is
hereby made for a description of the rights, limitations of rights, obligations,
duties and immunities thereunder of the Trustee, the Company, the Guarantor and
the Holders of the Security. By the terms of the Base Indenture, the Securities
are issuable in series that may vary as to amount, date of maturity, rate of
interest and in other respects as provided in the Base Indenture. This Security
is the series designated on the face hereof (the "Notes") and is limited in
aggregate principal amount as specified in said First Supplemental Indenture.

            In case an Event of Default, as defined in the Base Indenture, shall
have occurred and be continuing, the principal of all of the Notes may be
declared due and payable, in the manner, with the effect and subject to the
conditions provided in the Base Indenture.

            The Base Indenture contains provisions permitting the Company and
the Trustee, with the consent of the Holders of not less than a majority in
principal amount of the Outstanding Security of each series affected, to execute
supplemental indentures for the purpose of adding any provisions to the Base
Indenture or of modifying in any manner the rights of the Holders of this
Security; provided, however, that no such supplemental indenture shall (i)
change the Stated Maturity of the principal of, or any installment of principal
of or interest on, this Security, or reduce the principal amount thereof or any
premium payable upon the redemption thereof or the rate of interest thereon, or
to reduce the amount of principal of an Original Issue Discount Security that
would be due and payable upon a declaration of acceleration of the Maturity
thereof pursuant to Section 502 of the Base Indenture, or change any Place of
Payment where, or the coin or currency in which, any Security (or premium, if
any, thereon) or the interest thereon is payable, or impair the right to
institute suit for the enforcement of any such payment on or after the Stated
Maturity thereof (or, in the case of redemption, on or after the Redemption
Date); or (ii) reduce the percentage in principal amount of the Outstanding
Security of any series, the Holders of which are required to consent to any such
supplemental indenture or to waive certain defaults thereunder and their
consequences provided for in the Base Indenture; or (iii) modify any of the
provisions of the Base Indenture relating to supplemental indentures that
require consent of Holders, the waiver of past defaults or the waiver of certain
covenants, except to increase any such percentage or to provide that certain
other provisions of the Base Indenture cannot be modified or waived, without the
consent of the Holders of each Outstanding Security affected thereby, provided,
however, that the consent of the Holders shall not be required with respect to
changes in the references to "the Trustee" in Sections 802 and 908 of the Base
Indenture with respect to the deletion of this proviso from the Base Indenture,
in accordance with Sections 608(b) and 801(7) of the Base Indenture. The Base
Indenture also contains provisions permitting the Holders of not less than a
majority in principal amount of the Outstanding Security of any series affected
thereby, on behalf of all of the Holders of the


                                      B-4
<PAGE>
Security of such series, to waive any past Default under the Base Indenture, and
its consequences, except a Default in the payment of the principal of, premium,
if any, or interest on any Security of such series or a Default in respect of a
covenant or provision of the Base Indenture which cannot be modified or amended
without the consent of the Holder of each Outstanding Security of such series
affected. Any such consent or waiver by the registered Holder of this Note
(unless revoked as provided in the Base Indenture) shall be conclusive and
binding upon such Holder and upon all future Holders and owners of this Note and
of any Note issued in exchange therefor or in place hereof (whether by
registration of transfer or otherwise), irrespective of whether or not any
notation of such consent or waiver is made upon this Note.

            No reference herein to the Base Indenture or First Supplemental
Indenture and no provision of this Note or of the Base Indenture or First
Supplemental Indenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay the principal of and premium, if
any, and interest on this Note at the time and place and at the rate and in the
money herein prescribed.

            As provided in the Base Indenture and subject to certain limitations
therein set forth, this Note is transferable by the registered Holder hereof on
the Security Register of the Company, upon surrender of this Note for
registration of transfer at the office or agency of the Trustee in New York, New
York duly endorsed by the registered Holder hereof or accompanied by a written
instrument or instruments of transfer in form satisfactory to the Company and
the Security Registrar duly executed by the registered Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Notes of this
series of authorized denominations and for the same aggregate principal amount
will be issued to the designated transferee or transferees.

            No service charge will be made for any such transfer, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in relation thereto.

            Prior to due presentment of this Note for registration of transfer
of this Note, the Company, the Trustee, and any agent of the Company or the
Trustee may treat the registered Holder hereof as the owner hereof (whether or
not this Note shall be overdue) and neither the Company, the Trustee nor any
such agent shall be affected by notice to the contrary.

            No recourse shall be had for the payment of the principal of or the
interest on this Note, or for any claim based hereon, or otherwise in respect
hereof, or based on or in respect of the Base Indenture, against any
incorporator, stockholder, officer or director, past, present or future, as
such, of the Company, the Guarantor or of any predecessor or successor
corporation of either the Company or the Guarantor, whether by virtue of any
constitution, statute or rule of law, or by the enforcement of any assessment or
penalty or otherwise, all such liability being, by the acceptance hereof and as
part of the consideration for the issuance hereof, expressly waived and
released. Such waiver may not be effective to waive liabilities under the
federal securities laws.

SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF
NEW YORK.

unconditionally guaranteed (i) the due and punctual payment of the principal of
and interest on the Notes, whether at maturity, by acceleration or otherwise,
the due and punctual payment of interest on the overdue principal and interest,
if any, on the Notes, to the extent lawful, and the due and punctual performance

Indenture by the manual signature of one of its authorized officers.

shall have the meanings assigned to them in the Base Indenture or the First
